Group 1 patients, ...

PURPOSE: Spontaneous ureteral stone passage often causes severe renal colic, especially when the stone passes through the narrow ureteral orifice. In these situations noninvasive anesthesia-free, analgesia-free and radiation-free extracorporeal shock wave lithotripsy (ESWL) (Dornier Medical Systems, Marietta, Georgia) is a valuable tool. It can be performed at any time without ...

BACKGROUND AND PURPOSE: When intervention is necessary, controversy remains as to the best treatment modality for stones of the distal ureter. In general, ureteroscopy is favored over extracorporeal shockwave lithotripsy (SWL) as the treatment of choice for distal ureteral stones. Although uncommon, ureteroscopy failures have traditionally necessitated repeat ureteroscopy to ...

The ...

BACKGROUND AND PURPOSE: Clearance of lower pole stones and complex maneuvers such as basket repositioning remain challenging in ureteroscopic treatment of caliceal stone burdens. We describe the initial use of flank position ureteroscopy (FPU) with modifications to aid in the treatment of complex caliceal urolithiasis. We hypothesized that gravitational force ...

This prospective study was performed to evaluate the short-term results of patients undergoing SWL with the Dornier Compact Delta lithotripter for all renal calculi. PATIENTS AND METHODS: Between April ...

<b>Introduction: </b> Staghorn renal stones in a developing country, very often associated with insidious growth, late presentation, complications and recurrence, present an economic burden to the patient and a challenge to the treat-ing surgeon. Despite proven effectiveness of modern endourological procedures, they are cost intensive and require multiple sittings. Current ...

We study the outcome of 2,700 patients treated for 3,093 urinary calculi over a period of 60 months.

The optimal treatment of patients with lower pole renal calculi is still being defined. Shock wave lithotripsy, percutaneous nephrolithotomy, and ureteroscopy are all currently utilized to treat patients with this condition. These methods have yielded varying degrees of success. The influence of collecting system anatomy on shock wave lithotripsy results ...

MATERIALS AND METHODS: A total of 99 patients with ureteric stones at different levels ...

The Siemens Lithostar Litotriptor was used to treat 6 children with cystine nephrolithiasis, previously treated by open surgery. Five children had renal calculi (3 multiple caliceal, 2 pelvis) and one had ureteral calculus. Stone size ranged from 0.2-2.5 cm in diameter, and stone burden was from 0.24 to 10.81 cm3 ...

The current treatment of hereditary hemochromatosis (HH) consists of performing periodic manual whole blood phlebotomies. Erythroapheresis (EPH) is considered to be an alternative procedure if the classic treatment is contra-indicated. A prospective study of 13 consecutive cases of HH were included in a periodic EPH program with the aim of ...

BACKGROUND: Gallbladder stones are a well-known and widely studied problem in children. Hematological disorders are the most common diseases that can cause cholelithiasis. However, in the last few years, the proportion of children with idiopathic cholelithiasis has increased 50%. Herein, we present a prospective study on laparoscopic cholecystectomy in a ...

Stones of the renal pelvis can be treated either by extracorporeal shock wave lithotripsy (SWL) or percutaneous nephrolithotomy (PCNL). As a low-risk procedure with a longer treatment period, SWL often leads to persistent residual stone fragments, whereas conventional PCNL achieves a higher stone-free rate and allows a shorter treatment period ...

OBJECTIVE: To assess the efficacy and safety of the retrograde ureteropyeloscopic holmium laser for treating renal stones that are too large to treat with extracorporeal shock wave lithotripsy (ESWL). PATIENTS AND METHODS: Thirty patients (22 men and eight women, mean age 43 years, range 18-62) with a renal stone burden ...

Failure to differentiate between the different types of lumbosacral lipomas may lead to inaccurate assumptions and inappropriate management of patients. The goal of this study was to determine whether there is a difference in clinical outcome between patients with lipomyelomeningocles, intraspinal lipomas, and lipomas of the filum terminale. One hundred ...
